Who Are We?
SKM
Systems Analysis, Inc. is a California-based corporation founded in
1972 by three progressive engineers with a desire to automate
electrical design calculations. They originally developed the DAPPER
power system analysis software on a mainframe at the UCLA Computer
Center. By 1978, DAPPER was running in time-share mode on the Control
Data Corporation mainframe, and being used by engineers both in the
United States and internationally.
